In this post we will show how to configure a compute node in OpenStack to launch Docker containers. We assume that you already have a working OpenStack installation. The configuration we describe below worked for OpenStack Juno, while the controller and compute nodes were running Ubuntu 14.04 LTS.

Now, check instances in Openstack Horizon to see our newly created instance is running. Then, assign a floating IP address through Openstack horizon and try http://<assigned_ip>/ to see if it is working.
